To all whom it may concern Be it known that I, WALTER JAMES WAKE, a subject of the King of Great Britain, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Machines for Pasting and Trimming Wall-Paper, of whichthe following is a specification.

My invention relates to improvements in machines for pasting and trimming wall paper, and the principal objects of my invention are, first, to construct a machine of this class which will distribute the paste a uniform thickness on the paper, so that ultimately when the paper is pasted on the wall, there will be no paste to squeeze beyond the edges thereof; second, to provide a particular design of roller for distributing paste over the paper; third, to trim the selvage from the paper after the paper has been coated with paste, thus enabling me to feed coated paper in a very positive manner to the rotary cutters; fourth, to positively drive the rotary cutters so that the edges of the paper will be cleanly cut; fifth, to provide particular means for adjusting the position of the rotary cutters so as to cut the pattern to match; sixth, to positively feed the coated paper from the machine in a smooth and unwrinkled condition; 'seventh, to greatly lighten the construction of machines of this class without in any wise sacrificing strength and durability, and eighth, to construct the frame so that the machine may be opened up for'the purpose of cleaning, and the construction of my machine will be hereinafter particularly set forth, and what I claim as new will be pointed out in the claims,

Figure 1 is a front elevation of my machine, certain parts being broken away. Fig. 2 is a plan view of my machine, certain parts being broken away. Fig. 3 is a vertical cross section on the line 3-3 Fig. 2, showing the paper in process of being coated with paste and the selvage cut therefrom. Figs. 4 and 5 are end elevations of both ends of the machine, certainparts being removed to illustrate internal construction Fig. 6 is a vertical longitudinal section on the line 66 Fig. 2, and Figs. 7 and 8 are cross sections through portions of Wall paper coated with paste, and hereinafter particularly explained.

In the drawings like characters of reference lndicate corresponding parts in each figure.

A is any suitable paste receptacle, and the same is preferably mounted on the suitable legs B carried by the receptacle. The receptacle A is stoutly built, and secured thereto is a suitable frame 0. I show this frame as secured to the receptacle A and around the upper portion thereof, by suitable fastening means, such as screws D. As illustrated in the drawings, this frame projects beyond the front side of the receptacle A, and provides supporting means for the rollers hereinafter specifically referred to. Positioned within the receptacle A and secured to the side members E of the frameC are a pair of plates F, which plates are positioned one at each end of said receptacle. Mounted in the said plates is the axle G of the feed roller H. This feed roller of course operates to feed the distributing roller I with paste, coating the outer surface thereof, as the said distributing roller is in contact with the outer surface of said feed roller. The said distributing roller is mounted on a shaft J which is mounted in suitable plates K secured by screws L or equivalent fastening means to the outer side of the side members E. As will be seen upon referring particularly to Fig. 2, the upper ends of the plates F and K overlap the top edge of the said members E thus providing lips M which ride upon the top of said side members.

N are screws or other equivalent means whereby the plates F are secured to the said members E. The upper ends of the plates K and F are provided with elongated holes 0 which permit of the movement of these plates so as to adjust the position of the rollers H and I.

' P is the platen and the same is keyed to the driven shaft Q, which is journaled in the @iplates R which are secured by the screws or for other fastening means to the side memfibers E. The outer surface of the platen P i iis smooth.

' T is a roller keyed to the shaft U, which haft has bearing in the plates V suitably seoured to the side members E. The cutting or trimming disks are positioned in pairs L-Qat each end of the roller '1, so that as the coated paper passes over said roller, the selvage will be cut therefrom.

2 is the lower cutting disk, and the same is provided with a hub 3 which is suitably keyed to the shaft U.

4 is the upper cutting disk, and the same is provided with a stub shaft 5 on which is mounted a sleeve 6 which is screwed into the plate 7.

8 is a plate corresponding to the plate 7, and these plates are spaced apart by the spacing blocks 9. Any suitable means such as screws 10 are used to tie the plates 7 apd 8 together, and the said screws pass through the blocks 9. As illustrated clearly in Fig. 6 the stub shaft 5 and hub 3 extend through the plates 7 and 8, and splined on the stub shaft 5 by the feather key 11 is the pinion 12 which meshes with the pinion 13 keyed by the pin 14 on the hub 3. The said pinions are positioned between the plates 7 and 8, and when the shaft U is rotated, the said cutting disks at each end of the said roller T are rotated, thus positively severing the selvage from the paper by a clean cut.

S is a plate forming part of one of the plates R at one end of the receptacle A and on the outside thereof. Carried by this plate is a stub shaft 15 on which is mounted the drive wheel 16 provided with any suitable handle '17 This drive wheel meshes with the pinion 18 keyed to the driven shaft Q. Also keyed to said driven shaft Q is a pinion 19 which meshes with the pinion 20 keyed to the shaft J.

21 is an idler journaled on the stub shaft 22 which is mounted in the plate 23 carried by and depending below one of the side members E. Meshing with the idler 21 is a pinion 24 which is keyed as shown at 25 to the shaft U. By the train of gearing just described the various rollers with the exception of the feed roller H, as well as the cutting disks, are rotated. In order to drive the feed roller H, I key a pinion 26 to the shaft J, and this pinion is in mesh with the gear wheel 27 carried by the roller H.

The roll of wall paper 28 is mounted on the rod 29 which is held in the brackets 30, each suitably secured to each end of the receptacle A. The saidroll is positioned between the disks 31 and 32, one keyed to the rod 29 and the other loosely mounted thereon. The disk 32 is held by the coiled spring 33 (mounted on said rod and between the said disks and the collar 34 keyed to said rod), against one end of the roll 28, V and performs the function of a brake. The

construction just described permits of rolls of different lengths to be mounted on the rod 29, and it will be understood that this rod may be removed from its brackets 30 in any of the well-known ways. The paper is passed between the distributingroller I and the platen P, over this platen and over of different widths.

the roller T, and the end thereof passed over the front bar 35 of the frame C; By turning the handle 17, through the train of gearing before described, the paper is fed between the distributing roller I and platen P, and as this distributing roller comes in contact with the paper, the same is coated with paste. As the paper is passed over the roller T, the pairs of cutting disks 2 and 4 ateach side of the machine operate to sever the selvage 36. A certain amount of paste adheres to this selvage, and this added weight to the selvage causes the same to pass underneath the front bar 35 substantially in the manner illustrated in Fig. 3.

37 is an idler rod, the ends of which rest in the bottom of the slots 38 formed in the upper portions of the plates R. Keyed to said idler rod are a pair'of rollers 39. These rollers operate against the platen P, and as they are spaced apart a greater distance than the length of the distributing roller 1, they operate against the selvage as the paper is passed through the machine. Carried by one end of the platen P is a flange 40, and adjustablymounted on said platen is a flange ring 41. The width separating the flange 40 and the flange ring 41 is substantially that of the width of the paper, and these parts, together with the rollers 39 coact to guide the paper and prevent it from crumpling.

. To further help in the feedingof the coated paper out of the machine, and to hold the same in position against the roller T when the cutting disks are in operation, I provide a plurality of idler rollers 42 of any suitable construction. for these rollers, and the mounting means therefor, is as follows: Each idler roller is mounted on a spindle 43; the ends of each spindle pass through the ends 44 of the frames 45, and are suitably secured in place. The said idler rollers, together'with their spindles, are free torotate in said'frame.

exerts suflicient tension against the barf49 to maintain theidler rollers 48 in contact with the paper, as the same is fed over the front bar 35 largely by thefroller T.-: The

My preferred construction .110: Secured to each frame 45 is a coupling bar. 7

coupling bars of the intermediate idler rollers 42 are positioned above the bar 49, so that the idler rollers 42 may be thrown back out of contact with the'rollerrT when if it is desired to cut the paper'at any given point longitudinally so as to'provide'paper I claim nothing new on the means for cutting the paper longitudinally, and so have not shown any means for this purpose.

It is of great importance in a machine of this type to insure that the same coats the paper with the required amount of paste uniformly over all its surface, so that when the paper is pasted on the wall, there will be no danger of any surplus paste escaping from each side of the strip. I have found from actual experiment that a distributing roller with a smooth surface does not give as good results in coating the paper with paste as does a roller provided with a plurality of corrugations in its surface running longitudinally thereof. In Fig. 3 particularly the corrugations in the surface of the distributing roller I are shown somewhat enlarged.

In Fig. 7 I show, on an enlarged scale, the paper provided with a coating 51 of paste, and it will be noticed that the surface of this coating is more or less corrugated, and that this coating extends uniformly for the length and width of the surface coated. The result is that the pressure applied by the brush during the actual step of pasting the paper to the wall distributes the paste in such a manner that the ribs of'paste are forced into the troughs or grooves between each rib, thus making the layer of paste of uniform depth. The result is that there will be no surplus paste to be squeezed out at the sides of each strip as it is being pasted on the wall. On the other hand, when a distributing roller with a smooth surface is used, the paste is applied to the paper in the form of a plurality of ridges 52 spaced a considerable distance apart, and the surface of the paper separating said ridges is coated with a more or less uniform layer of paste. The result is that as there is too much paste at the ridges 52, when the paper is being pressed against the wall, the ridges are smoothed down, and at the same time part of the paste escapes out each side of the paper, thus making a very untidy job. Although in Fig. 8 the ridges 52 are shown of a substantially uniform height and a uniform distance apart, in actual practice I have found that the height of the ridges varies as well as the distance separating the same, and these ridges do not always extend at right angles to the edges of the paper.

The surface of each idler roller (which idler rollers are preferably made of rubber), is provided with a plurality of corrugations 53 extending substantially longitudinally thereof, and these corrugations are substantially of the same depth as the corrugations of the distributing roller I. The said idler rollers come in contact with the coated surface of the paper, and by reason of the corrugations thereof I insure that the pasted surface of the paper as it passes from the machine over the front bar 85 is provided with corrugations already mentioned and illustrated in Fig. 7. The idler rollers keep the pasted paper in contact with the roller T and so assist the same in feeding the pa per over the bar 35.

To cut the required length of pasted paper, I provide the following preferred means: 55 is a carriage provided with a finger grip 56. This carriage is provided with two pairs of legs 57 each spaced apart, and straddling the track 58, which track is secured by the screws 59, or equivalent means to the plates V. Mounted between each pair of legs 57 is a cutting disk 60, by means of a pin 61 which is held in the said legs. By providing the pair of cutting disks, I give the carriage 55 along bearing on the track 58 so as to prevent the same from binding. Since the said cutting disks operate against the front bar 35 over which the pasted paper passes, it will be understood the same may be used to sever the paper at any required point. Since the car riage 55 does not ride upon the top of the track-58, space is allowed for the applying of pressure to said cutting disks.

It will be seen particularly upon referring to Figs. 1 and 6 that a coiled spring 0 is mounted around each of the sleeves 6, and

exerts pressure against the cutting disks 4. This spring insures that the said cutting disks shall positively co-act to provide a clean cut.

One of the objects of my invention is to provide adjusting means for the cutting disks, so that the pattern may be cut to match. It sometimes occurs in the printing of wall paper that part of the pattern is printed nearer to one side of the paper than to the other side, and in such a case the said cutting disks must be adjusted to cut the pattern to match. My preferred means for adjusting the cutting disks is as follows: One end of the shaft U is reduced to form a shoulder (Z, and mounted on this reduced end 6 is an adjusting member f provided with an exteriorly threaded portion 9 which operates in the threaded hole it formed in one of the plates V. 2' is a screw tapped into the reduced end 0 of the shaft U and the head j of this screw is countersunk in the adjusting member 7, thus locking this adjusting memher to said shaft U. The bearing means for the cutting disks 2 and 4 at the left hand side of the machine illustrated in Fig. 2 is spaced apart from one of the side members E so that when the adjusting member 7 is moved to shift the shaft U, the parts carried by this shaft can be shifted to adjust the position of the said pairs of cutting disks for the purpose set forth.

In order to guide the bearing means composed of the plates 7 and 8, at each side of the machine, to hold the same in a perpenplaten co-acting dicular position, I provide the following preferred means. This means comprises rails m which are preferably integrally formed with the track 58. These said rails operate in notches it formed in the top of the plates 7 and 8 and the upper spacing blocks 9, thusholding the said plates in vertical position. The front wall of the receptacle A is provided with a backward curved breast 1) over which the paper passes with very little friction.

As before set forth, one of the objects of my invention is to enable my machine to be readily cleaned. N ow for this purpose the side members E are hinged as shown at 1' to the ends .9 of the back member 1' of the frame C. By lifting on the front bar 35 all of the rollers before describedare raised up far enough to facilitate the cleaning of the machine.

According to my method of driving the various rollers mentioned, there is a thrust upward on the hinged portion of the frame and to prevent the drive wheel 16 getting out of mesh with the pinion 18, I latch the front portion of the frame C to the receptacle A by any suitable means. My preferred construction comprises a latch 1 pivoted at a; to the plate 23, and hooked at its lower end over the pin y carried by one of the brackets 30. Suitable means for sup porting the movable portion of the frame C may be provided. My preferred construction for this purpose, at one side of the ma chine, comprises a lug 10 carried by the plate S which rests against the top of the upright member Z of one of the brackets 30. The upright member of the other bracket 30 is provided with a step 71 which receives the foot 72 of one of the brackets R.

From the foregoing specification it will be understood that I provide a cheaply constructed yet efficient machine for the purpose specified, and one which in its operation essentially coats the paper with paste before the selvage is trimmed off. that Iam enabled to pass the selvage out of the machine, thus keeping it free of accumulation therewith. Furthermore since the selvage is made damp by the paste, it is much easier to handle than when it is trimmed off in a dry state.

Various changes in construction may be made in my machine without departing from the spiritof my invention.
